DNA tests have now become mandatory in Kuwait for citizens and foreign residents, following a suicide bomb attack last week that claimed 26 lives.
The Kuwaiti parliament adopted the new law on Wednesday, as a step to ease arrests carried out by security forces, in cases of criminal offense or terrorism.
Kuwait currently hosts 2.9 million foreign residents, contiguous with its 1.3 million citizens.
The law envisages up to $33,000 in fines or one year imprisonment for those who fail to give samples of their DNA. The law also foresees seven years imprisonment for those who provide fake samples.
"We have approved the DNA testing law and approved the additional funding,” said Kuwaiti MP Jamal al Omar, and added, “We are prepared to approve anything needed to boost security measures in the country."
The expenditures of the interior ministry will be covered by a $400 million emergency funding that was approved by the parliament.
A suicide attack took place in the country last week during the weekly congregational Friday prayer at a Shiite mosque in the capital, killing 26 people and injuring 227 others.
According to Kuwaiti officials, the aim of the attack was to trigger sectarian conflict in the Sunni majority state.
ISIS claimed responsibility for the attack.
The man who carried out the suicide attack is reported to be Saudi-born Fahd Suleiman Abdulmohsen al Qabaa who goes by the name Abu Suleiman al Muwahhid.
Kuwait has put in place "all security measures, especially around mosques and all places of worship," according to Interior Minister Sheikh Mohammad.
"We are in a state of war. Yes, we have busted this terror cell but there are other cells we are
going to strike," he added.
Kuwait had been accused of being "the epicentre of fund-raising for terrorist groups in Syria" by the US Treasury Under Secretary for Terrorism and Financial Intelligence David Cohen.
